Kev txhaj tshuaj molding yeeb nkab fittings feem ntau ntsib qhov tshwm sim uas cov pwm tsis tuaj yeem sau rau hauv cov txheej txheem ntawm kev ua haujlwm. Thaum lub tshuab txhaj tshuaj molding tsuas yog pib ua haujlwm, vim tias pwm kub qis dhau lawm, qhov kub poob ntawm cov khoom siv PVC molten yog loj, uas yog nquag mus rau thaum ntxov solidification, thiab qhov tsis kam ntawm pwm kab noj hniav yog loj, thiab cov khoom tsis tuaj yeem. sau cov kab noj hniav. Qhov tshwm sim no yog qhov qub thiab ib ntus. Nws yuav ploj mus tom qab kev txhaj tshuaj tas li ntawm cov pwm digital. Yog tias cov pwm tsis tuaj yeem sau tau txhua lub sijhawm, xav txog cov xwm txheej hauv qab no thiab hloov kho kom tsim nyog:

Ua npuas ncauj ntawm cov yeeb nkab

Thaum tshav kub kub npuas yog tsim los ntawm cov cua kub kub. Cov txheej txheem kub dhau heev yuav ua rau npuas hauv cov volatiles nyob rau hauv cov ntaub ntawv raw, thiab yuav ua rau ib nrab decompose.PVCcov khoom siv los tsim npuas, uas feem ntau hu ua npuas npuas. Tsim nyog kho qhov txhaj tshuaj ceev

Kev txhaj tshuaj nrawm dhau lawm. Vim cov txheej txheem molding ntawmPVC-Utxhaj tshuaj molded cov khoom yuav tsum tau txais kev txhaj tshuaj qis dua thiab kev txhaj tshuaj ntau dua. Kev txhaj tshuaj nrawm tuaj yeem hloov kho kom haum.

Yog hais tias lub rooj vag me dhau los yog qhov ntws channel seem me dhau, cov khoom ntws tsis kam yog loj dhau. Lub rooj vag thiab lub rooj sib tw khiav tuaj yeem nthuav dav kom txo tau cov dej ntws tawm.

Cov ntsiab lus ntawm cov dej noo los yog lwm yam teeb meem nyob rau hauv cov ntaub ntawv raw yog siab dhau lawm los yog cov ntaub ntawv raw tau khaws cia ntev dhau lawm, thiab cov dej noo hauv huab cua yog absorbed. nruj me ntsis tswj cov ntsiab lus ntawm volatiles nyob rau hauv cov ntaub ntawv raw thaum yuav cov khoom siv raw, thiab cov khoom siv raw thiab cov khoom siv yuav tsum tsis txhob muab khaws cia ntev dhau rau lub sijhawm lossis thaj chaw uas muaj cov av noo siab hauv huab cua.

Cov khoom tsis zoo gloss

Qhov saum npoo gloss ntawm PVC txhaj tshuaj molded cov khoom muaj feem cuam tshuam nrog cov dej ntawm cov ntaub ntawv PVC. Yog li ntawd, kev txhim kho fluidity ntawm cov ntaub ntawv yog ib qho tseem ceeb ntsuas los txhim kho cov khoom. Vim hais tias qhov kub ntawm cov khoom molten yog tsawg thiab cov fluidity ntawm cov khoom tsis zoo, cov cua kub ntawm cov khoom yuav tsim nyog, tshwj xeeb tshaj yog kub ntawm lub nozzle.

Cov mis yog tsis tsim nyog, yog li ntawd cov plasticization ntawm cov khoom tsis nyob rau hauv qhov chaw los yog muab tub lim ntau dhau lawm, cov mis yuav tsum tau hloov, thiab cov plasticization zoo thiab fluidity ntawm cov khoom yuav tsum tau txhim kho los ntawm cov tsim nyog ua ke ntawm kev pab, thiab tus nqi ntawm cov fillers yuav tsum tau tswj.

Tsis txaus pwm txias, txhim kho pwm txias nyhuv. Yog hais tias lub rooj vag loj me dhau los yog qhov kev sib tw khiav me dhau, qhov kev tiv thaiv loj dhau. Koj tuaj yeem ua kom qhov kev sib tw khiav kom tsim nyog, nce lub rooj vag, thiab txo qhov kev tawm tsam.

Cov ntsiab lus ntawm noo noo los yog lwm yam volatiles nyob rau hauv cov ntaub ntawv raw yog siab dhau. Cov ntaub ntawv raw tuaj yeem qhuav tag, lossis cov dej noo lossis cov volatiles tuaj yeem raug tshem tawm los ntawm cov khoom siv. Yog tias qhov tso pa tawm tsis zoo, qhov tso pa tawm tuaj yeem ntxiv los yog qhov chaw ntawm lub qhov rooj tuaj yeem hloov pauv.

Muaj qhov pom tseeb weld kab

Qhov kub ntawm cov khoom siv melted yog tsawg, thiab cov cua kub ntawm lub thoob tuaj yeem tsim nyog, tshwj xeeb tshaj yog qhov kub ntawm lub nozzle yuav tsum tau nce. Yog tias qhov kev txhaj tshuaj siab lossis kev txhaj tshuaj ceev qis, qhov kev txhaj tshuaj siab lossis kev txhaj tshuaj nrawm tuaj yeem tsim nyog.

Yog tias pwm kub qis, pwm pwm tuaj yeem ua kom tsim nyog. Yog tias lub rooj vag me dhau los yog qhov chaw hla ntawm tus neeg khiav dej num me dhau, koj tuaj yeem ua kom tus neeg khiav dej num loj dua lossis nthuav lub rooj vag kom tsim nyog.

Cov pwm tsis zoo, txhim kho pwm tso tawm kev ua haujlwm, ntxiv cov grooves tso tawm. Qhov ntim ntawm qhov dej txias txias yog qhov me me, yog li qhov ntim ntawm qhov dej txias txias tuaj yeem nce ntxiv kom tsim nyog.

Tus nqi ntawm lubricant thiab stabilizer nyob rau hauv cov mis yog ntau dhau lawm, thiab lawv cov nyiaj yuav raug kho. Qhov kev teeb tsa kab noj hniav tsis tsim nyog thiab nws qhov kev teeb tsa tuaj yeem hloov kho.

Cov cim dab dej hnyav

Gaoan qhov kev txhaj tshuaj siab tsawg, yog li qhov kev txhaj tshuaj tuaj yeem nce ntxiv kom tsim nyog. Lub sij hawm tuav lub sij hawm tsis txaus, koj tuaj yeem nce lub sijhawm tuav kom tsim nyog.

Lub sijhawm txias txias tsis txaus, koj tuaj yeem nce lub sijhawm txias kom tsim nyog. Yog tias tus nqi ntawm cov sol tsis txaus, nce cov sol kom tsim nyog.

Kev thauj mus los ntawm cov dej ntawm cov pwm tsis sib xws, thiab cov cua txias tuaj yeem hloov kho kom txhua qhov ntawm cov pwm txias sib npaug. Cov txheej txheem loj ntawm cov pwm qhov rooj yog qhov me me dhau lawm, thiab lub rooj vag tuaj yeem nthuav dav lossis lub ntsiab, ceg, thiab qhov sib tw khiav qhov ntev tuaj yeem loj tuaj.

Yooj yim rau demold

Qhov nyuaj ntawm demolding yog tshwm sim los ntawm cov pwm thiab cov txheej txheem tsis raug, tab sis feem ntau nws yog tshwm sim los ntawm qhov tsis tsim nyog demolding mechanism ntawm pwm. Muaj cov khoom siv sib txuas hauv lub tshuab demolding, uas yog lub luag haujlwm rau hooking tawm cov khoom txias ntawm lub ntsiab, khiav thiab lub rooj vag: lub ejection mechanism siv lub ejector pas nrig los yog lub phaj saum toj kawg nkaus eject cov khoom los ntawm cov pwm txav tau. Yog tias lub kaum sab xis demolding tsis txaus, demolding yuav nyuaj. Yuav tsum muaj pneumatic txaus siab thaum lub sij hawm pneumatic ejection thiab demolding. , Txwv tsis pub yuav muaj teeb meem hauv demolding. Tsis tas li ntawd, cov tub ntxhais rub cov cuab yeej ntawm qhov ntu ntu, cov xov tseem ceeb rub cov cuab yeej, thiab lwm yam yog txhua qhov tseem ceeb hauv cov qauv demolding, thiab tsim tsis tsim nyog yuav ua rau muaj kev nyuaj ntawm demolding. Yog li ntawd, nyob rau hauv lub pwm tsim, lub demolding mechanism kuj yog ib feem uas yuav tsum tau them sai sai rau. Nyob rau hauv cov nqe lus ntawm kev tswj cov txheej txheem, kub siab heev, pub ntau dhau, kev txhaj tshuaj siab dhau lawm, thiab lub sijhawm txias txias yuav ua rau muaj teeb meem demoulding.

Hauv cov ntsiab lus, ntau yam teeb meem zoo yuav tshwm sim hauv kev ua haujlwm ntawmPVC-Utxhaj tshuaj molded khoom, tab sis yog vim li cas rau cov teeb meem no nyob rau hauv cov khoom, pwm, qauv, thiab cov txheej txheem. Tsuav yog muaj cov cuab yeej ua tiav thiab pwm, cov qauv tsim nyog thiab cov txheej txheem, cov teeb meem tuaj yeem zam tau. Tab sis hauv kev tsim khoom tiag tiag, cov teeb meem no feem ntau tshwm sim, lossis tshwm sim yam tsis paub txog cov laj thawj thiab cov kev daws teeb meem, nyob ntawm kev sib sau ntawm cov kev paub dhau los. Kev ua haujlwm nplua nuj kuj yog ib qho ntawm cov xwm txheej los xyuas kom meej cov khoom zoo.
